Relationship between self-reported symptoms and clinical signs in the assessment of work-related musculoskeletal disorders

Abstract

This study aimed at verifying the relationship between self-reported musculoskeletal symptoms and clinical findings of work-related musculoskeletal disorders (WRMD). One hundred and thirty-two female
workers from an industrial company took part in the study, being excluded
those with previous diagnostics of rheumatic diseases. They answered a
questionnaire on symptoms in upper limbs and the cervical region. Physical examination included range of motion tests, manual palpation, and specific tests. Data were analysed descriptively; Spearman's test was applied to assess correlation between self reported symptoms and clinical findings. A positive correlation was found between these for all assessed body regions (r=0.61; p<0.05). This study shows thus a clear relationship between selfreported symptoms and clinical examination findings, pointing to the importance of using both methods in WRMD evaluation. Physical
examination is necessary to establish clinical diagnosis and self-reports
allow identifying the impact of WRMD on patients life.
